Stop Measuring Cost Per Lead. Measure Cost Per Showed Appointment.
Cost per lead is the most quoted and least useful number in dealership marketing. It is trivially easy to make it look good and it tells you almost nothing about whether the channel is making money.
Here is the math that actually matters, and how to run it on your own numbers this afternoon.
The quick answer
Cost per lead rewards volume regardless of quality. Cost per showed appointment and cost per unit sold reward revenue. Calculate total channel spend divided by showed appointments, then divide by close rate to get cost per unit, and compare that against your combined front and back gross. Any vendor that reports only cost per lead is optimizing for a number that does not pay your floorplan.
Why cost per lead lies
Cost per lead can be cut in half tomorrow by loosening the offer, widening the audience and switching to an instant form. Volume goes up, cost per lead goes down, the report looks fantastic, and your BDC drowns in people who filled out a form to see a payment and never intended to buy. Nothing about the store's revenue improved.
The funnel, stated as multiplication
- Leads x contact rate = conversations
- Conversations x set rate = appointments
- Appointments x show rate = showed appointments
- Showed appointments x close rate = units
Every stage is a multiplier, which means a weak stage anywhere collapses the whole chain. It also means improvements compound: lifting show rate from 50 to 65 percent and close rate from 25 to 30 percent produces a bigger unit gain than doubling lead volume, at zero additional media cost.
The two numbers to report
Cost per showed appointment
Total channel cost, including management fee and media, divided by showed appointments. This is the honest measure of a marketing channel, because a showed appointment is the last event the marketing is responsible for. What happens after that is on the floor.
Cost per unit sold
Cost per showed appointment divided by your close rate on those appointments. Compare it directly to combined front and back gross. If cost per unit is a fraction of gross, the channel is profitable and the only question is how far you can scale it before quality degrades.
Worked example
Suppose a channel produces 40 showed appointments in a month at a total cost of $6,000. Cost per showed appointment is $150. At a 25 percent close rate that is 10 units, or $600 per unit. Against a combined gross of $3,500 per unit, the channel returns roughly six dollars for every dollar spent. Now run the same math on your third-party lead provider and compare.
Attribution discipline
- Tag every lead source at creation and never let it be overwritten by the last touch
- Log the showed appointment as a distinct CRM event, separate from the set
- Reconcile sold units against source monthly with the desk, not quarterly
- Count multi-visit and referral deals back to the originating source
Most dealerships underreport their best channel because a buyer who came from a Spanish ad called the store directly on their second visit and got logged as a walk-in. Fixing attribution frequently changes budget decisions more than any campaign change.
How Hispanic Drive helps
Hispanic Drive runs full-funnel reporting from ad spend to showed appointment for dealerships as a managed channel. We build the Spanish creative, run the Meta and WhatsApp campaigns, staff the bilingual BDC that answers every lead, qualify the buyer, book the appointment, confirm it, and follow up after the visit. Your team does what it already does well: sell cars to the people who walk in.
We work with one dealership per market. If the Hispanic buyer in your city is currently going somewhere else, a strategy call is the fastest way to find out what that is costing you every month.
